Question

velocity is given by v=Pt + Qt^2 , where t is time .what are the dimensions of P and Q?

Answer 1

dimensions given are

$v = l {t}^{ - 1} \\ t = t \\ v = pt + q {t}^{2} \\ using \: dimension \: correctness \: formula \\ then \\ v = pt \: \: \: \: and \: v = q {t}^{2} \\ from \: equ. \: \\ v = pt \\ we \: can \: write \\ l {t}^{ - 1} = p \times t \\ or \: p = \frac{l}{t \times t} \\ or \: p = l {t}^{ - 2} \\ from \: equ. \\ v = q {t}^{2} \\ we \: can \: write \: l {t}^{ - 1} = q \times {t}^{2} \\ or \: q = \frac{l}{t \times {t}^{2} } \\ or \: q = l {t}^{ - 3}$
